Well guys. This maybe it for my car. IT'S LEAKING COOLANT INTERNALLY! Ohhhhh boy. not good. What do I need to replace? I"m soo mad now. I've read on the internet that when there's yellow gunk on the oil fill cap, that means there's a coolant leak. Will this be pricey to fix? Geez. I love my car soo much, and this happens. Why can't it just give me a little casualty like bad starter?

 

could just be the head gasket couldnt it?

 

yes it could, and more than likely is. not a HUGE issue, still a pain in the ass though.

 

Well, I'm going to do an Oil analysis to make sure it's not coolant. It could be just moisture. I'm keeping my fingers crossed.

 

Headgasket probably.

Not so bad.

 

Instead of doing your oil analysis do a leak down test. You'll get way more information from a leakdown test than analyizing your oil.

 

this guy i used to work with had that problem. his car still drove, but year definitely could be head gasket.

 

^ How can do a leakdown test when the coolant leak is possibly internal?

 

Leakdown test will tell whether or not the headgasket is blown.

 

Is it just on the cap? Hard to tell in pic but looks like froth from moisture which is very common with the change of seasons from warm to cold. Should be fine, just do an oil change and run a cleaning additive, keep an eye on it and see if it comes back.
